Final answer:
The ozone layer in the Earth's stratosphere absorbs UV light from the sun, protecting life on Earth.
Step-by-step explanation:
The ozone layer in the Earth's stratosphere is responsible for absorbing ultraviolet (UV) light from the sun. This absorption helps to protect life on Earth by preventing most of the dangerous UV radiation from reaching the planet's surface. UVB, a type of UV light, is particularly harmful and has been linked to various negative effects, including skin cancers, cataracts, and harm to crops and marine life.
